4.2.5 Possible Time Schedule for Remedial Measures
To implement the temporary underdrain system, it will take several weeks to complete. The installation of the permanent subsurface drainage system may also take a few months. Besides the subsurface drainage system, the replacement of the damage asphalt pavements may require at least six months to complete. Therefore, it is very unlikely that the remedial works would be completed before the end of this year.
